zach and post ironic are best placed to advice, but I'd suggest changing to a better measurement system as lbs are retarded. 5kgs will be manageable for lower weighs, but post 70/80kgs you'll hurt yourself and/or develop bad form if you push too fast.

I just reread what you said. I've not read any plans that advise raising weights between sets, I've always understood that each set you got for the max you can lift for the amount of reps. I.e 5 sets of 5 reps of 110kgs, not 5 -60, 5 - 70, 5 - 80, 5- 90, 5 - 100, 5 - 110, that's a waste of effort.
